Painted Hills unit of
On one of my summer vacation bike trips around
in the Pacific Northwest, I visited the Painted Hills near Prineville in
central Oregon. Oregon's heartland is a geological paradise.
Mostly dry, as it lies on the east side of the Cascade Mountains, the region
is full of old falt lines, lava formations and other features that are preserved
and exposed by the dry climate. These mud hills are among the many
unusual things to see.
